The Harmony®Plug is a new revolutionary approach to Keith Louis Eichmann’s (aka KL) previous Bullet Plug design, which itself was a revolutionary approach to Phono/RCA connection. It represents a wholesale rethinking of something as basic as the venerable Phono/RCA plug; a connector designed over Sixty years ago by The Radio Corporation of America (RCA).
KL’s objectives to improving the humble RCA plug are… improved conductivity, enhanced signal integrity, higher resolution, and improved connection. These objectives are important and significant in critical areas of Electron Flow and Signal Integrity for High Resolution audio performance and requires close attention to all areas of Connector design, as follows…
Geometry/Materials/Mass – KL’s Signal/Ground formula/architecture, ensures Optimum mass of Metals and Dielectrics are used to avoid skin effect, maintain structural Strength and Reliability, and minimise Reactive, EF, & EMF effects. Controlling these effects ensures that a complete, full, and extended Signal frequency range, and their harmonics, are transmitted from Component to Component, which further ensures that the listener enjoys a complete, full, extended, detailed, involving, and musical presentation.
Metallurgy – we/KLEI do not waste the effort gained in the other aspects of our designs by compromising with metals less conductive than Copper or Silver.
Metal Conductivity %IACS (IACS – International Annealed Copper Standard)
The conductive pins of the Harmony®Plug are formed using our proprietary high conductivity alloys, the Copper alloy having an IACS Rating >101% and the Silver alloy having an IACS rating >106% to ensure the highest levels of conductivity. When compared to a typical gold plated brass connector used in the vast majority of deluxe Phono/RCA plugs, the Harmony RCA plug range, utilizing our proprietary alloys, achieve improvements in conductivity exceeding 320%. Proven metallurgical choices result in improved signal transfer, and electron flow, which is consistent with high resolution interconnect/digital cables.
KLEI’s proprietary high conductivity Copper/Silver alloys vs ‘Pure annealed Copper/Silver’…
Our Testing, and Reports we have received, are confirming…
Conventional RCA’s are designed with a Metal Collar, which is prone to electron turbulence called Eddy Currents. In addition to this Capacitive Reactance and Micro-Arcing are additional artifacts of the metal collar architecture.
Our proprietary high purity silver plating (>106% IACS) is applied directly to the conducting surfaces of the Harmony®Plug pins, as required. This produces the performance/sound characteristics of 4-nines pure silver (>106% IACS) and no additional plating is required to preserve signal quality.
KL believes he has, with this new KLEI Harmony Phono/RCA plug blueprint, solved a series of problems that collectively degrade audio/video performance and that do so in an additive manner. The importance of this innovation and redesign cannot be overstated. Its ramifications extend to every Phono/RCA interface in which high quality signal transfer is an issue. Extensive listening and critical comparisons played a major role in the evolution of the design, confirming at every juncture the audibility of properly applied science in even the area of Phono/RCA connection.
In summary the KLEI Harmony®Phono/RCA plug is a further innovation/revolution and totally new approach to Phono/RCA connection.

Beschreibung von Chris Veenhaus, VH audio, USA:
The Harmony® RCA Plug is a new revolutionary approach to Keith Louis Eichmann’s (aka KL) previous Bullet Plug design, which itself was a revolutionary approach to Phono/RCA connection. It represents a wholesale rethinking of something as basic as the venerable Phono/RCA plug; a connector designed over Sixty years ago by The Radio Corporation of America (RCA). It is KL’s contention that the Phono/RCA plug, in its current configuration is the standard connector in the audio/video industry not because it is the best possible choice for its intended use, but more by reason of default and its ultimate potential.
Realizing this to be the case, KL undertook a project of major significance: the wholesale redesign of this critically important but very compromised connector, with the objective being improved conductivity, enhanced signal integrity, higher resolution, and improved connection. Since the Phono/RCA plug is so widely used, connecting virtually every component in an audio/video chain, linking a multitude of components through a network of interfaces, any improvement in its performance in the critical areas of electron flow and signal integrity would be significant and particularly important in high resolution applications.
A first evaluation of the Phono/RCA plug pointed to obvious metallurgical shortcomings. Most connectors, even those marketed as “deluxe” upmarket Phono/RCA plugs, are made from nickel and gold plated brass or phosphor bronze with a conductivity rating typically less than 28% IACS (International Annealed Copper Standard). As a comparison, the high purity copper used in the vast majority of interconnect cables has a conductivity rating of 100% IACS. Because of this low conductivity and the use of three disparate metals, it is KL’s contention that standard Phono / RCA plugs, even very expensive Phono / RCA plugs marketed as “High-End”, compromise electron flow and diminish the performance of the components they connect.
In KL's opinion, nickel is added solely to provide the jewel like appearance that makes expensive connectors look expensive. While achieving the desired appearance, it comes at a cost, which is degraded sound or poorer picture quality, as electrons flow through three dissimilar metals with differing electrical and conductive properties.
The conductive pins of the Harmony�Plug in contrast are formed from high conductivity copper alloys (having >101% IACS), or from high conductivity silver alloys (having over >106% IACS) to ensure maximum conductivity. This provides >320% greater conductivity than the gold plated brass connectors used in the vast majority of deluxe Phono/RCA plugs. Proven metallurgical choices result in better signal transfer, and electron flow that is consistent with the highest quality interconnect cables.
Using a direct dense proprietary high purity hard silver plating on the conducting surfaces of the pure copper Harmony® Plug pins allows the elimination of the nickel/gold plating typically used as the third metals in a confusing composite on standard Phono/RCA plugs. The dense proprietary high purity hard silver plating (> 106% IACS) produces the performance/sound characteristics of 4-nines pure silver (>106% IACS) and no additional plating is required to preserve signal quality.
While the metallurgical understandings are significant, the second observation regarding the Phono/RCA plug turned out to be ground breaking. It related to a problem, overlooked for decades, that is intrinsic to the Phono/RCA plug’s design, and something as fundamental as the architecture of the RCA Socket itself. That is Phono/RCA ground collar, acting as a conductor that transfers electrons from multiple directions between the centre pin and its surface, are prone to electron turbulence called eddy currents. These turbulences are nothing less than electron chaos, exacerbated by the nonspecific point of ground in the Phono/RCA plug’s design, as an entire surface encircling the centre pin forms the electrical ground. Capacitive reactance and micro-arcing are additional artifacts of this architecture.
The Harmony® Plug addresses these issues and offers an elegant and arguably major solution to the Phono/RCA plug that is so fundamental and so extensive that we have been granted a patent. The solution being, rather than encircle the centre conductor pin with a formed metal collar as ground, KL opted for a single point ground contact similar to star earthing/ground in high-end electronics. KL’s Harmony design features a redesigned single point ground connection, which has an optimised shape, mass and thickness of the conductive elements, eliminates every vestige of eddy current turbulence, capacitive reactance, and micro-arcing.
KL believes he has, with this new Phono/RCA blueprint, solved a series of problems that collectively degrade audio/video performance and that do so in an additive manner. The importance of this innovation and redesign cannot be overstated. Its ramifications extend to every Phono/RCA interface in which high quality signal transfer is an issue. Extensive listening and critical comparisons played a major role in the evolution of the design, confirming at every juncture the audibility of properly applied science in even the area of Phono/RCA connection.
In summary the Harmony® Phono / RCA plug is a further innovation and totally new approach to Phono/RCA connection.
With the KLEI Pure®Harmony RCA plugs, initially, they have a tendency to be a little bright and more than a little edgy, at least on my system. It took around 20 hours for that to settle down and transform into a very smooth and incredibly detailed performance. Which was nice, because with 180 hours left to burnin I was giving some serious thought to installing the RCA’s onto an interconnect and letting my streamer and DAC complete the burn-in process, which is a much less time consuming approach. At around 30 hours I became very impressed with the performance improvements.
- The dynamics were very fast and extremely crisp.
- The image (sound stage) is deeper than before and there is more spacing between the instruments both left to right and front to back, ie. each “section” in the orchestra (ie. violins, violas, cellos etc.) have significantly more width to them.
- The timbre of instruments having more detail/resolution sounded even more natural.
- The venue acoustics are outstanding and really immerse you into the performance.
- The improved clarity in complex orchestral tracks allowed them to be played louder without distortion – 1812 with digital cannons anyone?
- But the one outstanding quality of the KLEI Pure®Harmony RCA plugs was their transmission of incredibly fine micro detail/resolution that seemed to bring a “new reality” to my vinyl collection, especially with some my older live recordings.
- It was apparent on the very first track I played when I dropped the arm and I was returning to my chair, but I never made it. As soon as the track started playing I spun around to listen more intently, standing, the sound was so totally different from any previous plays.
- The extremely fine details of the bottleneck sliding on the strings was just downright eerie, like a ghost from the past. Many tracks sounded as though they were recorded in a gospel hall with two mikes and a stereo reel-to-reel. The natural reverberations are melded superbly with the musicians and their vocals and then reproduced in my system with a haunting reality.
- For me, this was a complete jaw-dropper. I’d heard some very expensive systems that may have approached this level of reproduction, but I never expected my current configuration would be capable of such a refined and detailed presentation.
- And all this was due to the KLEI Pure®Harmony RCA plugs? – You got it!
The KLEI Pure®Harmony RCA plugs when compared to the KLEI Silver®Harmony RCA plugs…
- In very simple terms… everything got bigger, faster, and cleaner!
- The bass line now had added detail and texture, the cymbals were crisper and fuller, the mids were warmer, the dynamics were faster and the image just seemed more complete. There was an added punch to both the percussion and also to the hammering of the very muted guitar strings. Lastly, the vocal detailing is now very clear and very well isolated within the recording.
- The improvements I witnessed between my identical interconnects, one set with the KLEI Silver®Harmony RCA plugs and the second with the KLEI Pure®Harmony RCA plugs was immediately noticeable. Improvements in dynamics, clarity, image and bass extension, with a new fullness to the reproduction and a new reality in the performance.
- I’ve experimented with cables of several types over the years and used a variety of connectors, including the Silver Bullet, which I had rated very highly, and I have now tried the KLEI Copper®Harmony RCA plugs, which performed even better. The KLEI Silver ®Harmony RCA plugs again proved to be a significant improvement over the KLEI Copper®Harmony RCA plugs, but the level of performance the KLEI Pure®Harmony RCA plugs has achieved is the new benchmark in RCA connector performance.
- Achieving this level of performance simply with an RCA connector may sound unbelievable, almost Magical, and in my mind makes the team at KLEInnovations (KLEI)… The Wizards of Aus!
KLEI Pure®Harmony Phono/RCA plugs by Neville Roberts (Hi-Fi Choice/UK)
IT’S 60 YEARS since the original phono plug was designed by RCA. Now, hot on the heels of the entry-level Copper Harmony RCA plugs from KLEInnovations (HFC 388), come the Silver Harmony and Pure Harmony RCA plugs. The Eichmann Bullet RCA plug has gained a well-deserved reputation as a high-quality phono plug. One of its features is that, along with the likes of WBT, it has a single-point earth return contact. However, since the success of the Bullet, Keith Louis Eichmann (aka KL), the man behind the Eichmann Bullet, has launched KLE Innovations in Australia to produce a brand new range of products, including the Harmony RCA Plug. The range is the result of a project aimed at developing the design of the Bullet in order to improve conductivity and signal integrity across the connection.
Both the Silver and Pure Harmony build on the design philosophy of the Copper Harmony plugs, but use different materials for the contacts.
All of the Harmony range has an easy snap-like connection to a standard phono socket. The high melting point thermoplastic polymer housing assembly uses two grub screws (a small Allen key is required, but not supplied) and a small rubber collar to retain and secure the cable.
Internally, tag-shaped connections for the signal and earth facilitate the soldering of a wide range of cable types and configurations.
The entry-level Copper Harmonys employ KLEI PureCopper™ for the signal and earth pins.
Moving up in the range, the Silver Harmonys are identical, but use an earth connection made from KLEI PureSilver™ and KLEI PureCopper™ for the signal pin.
Finally, in the Pure Harmonys, both the signal and the earth pins are made from KLEI PureSilver™.
For the purposes of the test and in the interests of consistency, I fit all the plugs in turn to a set of interconnect cables made from Neotech STDST-24 UP-OCC stranded silver wire in Teflon sleeving and solder the plugs to the wire using Mundorf 3.8 percent silver solder.
Soldering is a piece of cake, thanks to the good design of the internal tags.
However, I do have one or two questions still running around my head, so I consult with the man himself. Thanks to an introduction from the UK importers, Black Rhodium, I put a few questions to KL. I first ask him how the new Harmonys differ from the famous Eichmann Bullets.
He explains that the main differences are in the materials and the internal layout of the pins. The Silver Bullet utilises machinable silver (<96 percent IACS), the Copper Bullet utilises machinable tellurium copper (<95 percent IACS) and the basic Bullet utilises machinable brass (<28 percent IACS). The Harmonys use a proprietary formula (and, so, secret) metals for the pins to offer enhanced conductivity and improve their physical strength.
Furthermore, the internal connections feature an anti-shorting shield and are arranged to maximise the distance from each other in order to minimise inductive, capacitive and EMF effects.
I then ask why he made the earth pin from KLEI PureSilver™ in the Silver Harmony plugs, rather than the signal pin. KL points out that the relationship between the signal and earth pin metals is not straightforward and this design is to achieve the best price/performance ratio.
I note that the earth pin extends up into the body and has a threaded section that engages with the plug housing, although the housing is plastic on all the models.
Is he planning on having a metal sleeve version in the future? He replies that he’s considering a future housing that will ensure star-point grounding to minimise the metal housing’s coaxial effects.
So much for the theory, the proof of the pudding is how they sound.
After running them in, I find that in comparison with the Copper Harmonys, the Silvers offer similarly excellent imaging, but seem to offer improved clarity and transparency to the sound.
The Pure Harmonys appear to take this improvement a stage further by opening up the sound stage. Bass drums also have better attack.
In my opinion, the Silver and Pure Harmony plugs are superb value for money, work extremely well and so come highly recommended. NR

KLEI Harmony Phono/RCA plugs by Totally Wired
Harmony Phono/RCA – the new standard in audio connections from KLEI.
KL (Keith Louis Eichmann) re-invented the ubiquitous RCA plug 15 years ago with his little Bullet Plug. Outside of the Silver Bullet version that quickly followed, it’s never been improved upon – copied, imitated and even forged, but never bettered. Until now.
We could ask, what took you so long? It’s not easy to improve on something that seems so blindingly simple and elegant, so if you want real improvement, then it’s going to take some serious thought and if you are the one that designed the original, the ability to stand back and look critically at what you have done and how it can be refined in meaningful ways.
The original Bullet plug uses an earth pin, rather than encircle the centre conductor pin with a formed metal collar as ground as with all other RCA plugs. KL’s Harmony design features a redesigned single point ground connection, which has an optimized shape, mass and thickness of the conductive elements.
Learning from the fact that the Silver Bullet plugs far outperformed the original gold plated versions KL has incorporated increasing silver content in the 4 new Harmony Plug designs. The entry level Copper Harmony appears to be silver but the two conductors are in fact plated. But the base material is high purity copper, whereas the original bullet plugs used Tellurium Copper which is significantly less conductive – and the gold plating dropped this further.
How great are the differences in conductivity in metals commonly used in connecting plugs? This is hugely important as any sound in an audio system comes from the movement of electrons – that’s what electricity is – and anything that gets in the way is bad news.
Pure Copper is regarded as being the standard for conductivity and has an arbitrary 100% value. And all that gold you see on audio plugs and sockets? – 65-75% – see a problem? The brass that hides underneath the gold plate almost all other plugs is at best 28%.
By way of comparison Pure Silver comes in at 105% – it’s a better conductor than even the most pure copper. Even if you just see that these new plugs are less of a barrier to music then you’ll be well on the way to understanding how and why they work.
Further refinements to the body of the plug, much easier to solder connections and better separation make the new Copper Harmony plugs actually sound better than the original Silver Bullets – for less than half the price.
The Silver Harmony Plugs move to a pure silver earth conductor while maintaining the silver plated copper positive. And the Pure Harmony plug is all high purity silver. The soon-to-arrive Absolute Harmony plug is simply as good as it gets.
Because of the improvements made to the physical designs, not only is the Copper Harmony Plug better than the original Silver Bullet, the difference between the Copper Harmony and every successive model is more obvious and worthwhile than that in the originals. All these plugs are now much easier to fit and use – everything is more solid and tactile, soldering is much simpler and the better positioning and profile of the solder tags means even a novice enthusiast is going to make a good job with them.
So who is likely to use these plugs? Our first experience of the early Bullet Plugs was a pair fitted to our turntable – the improvement this made was remarkable, so it follows that anyone with turntable should get in with a pair as quickly as they can. Likewise for anyone with any of the braided Kimber Interconnects – Tonik, PBJ, Silver streak and Ag – the construction of these makes fitting any of the new Harmony plugs a breeze – given that Kimber themselves have better plugs options on most of their cables, that’s a clear indication that better plugs are worthwhile.
The vast majority of interconnect cables out there will be greatly improved by the addition of the new Harmony Plugs – we’ve got high quality silver solder we’ll also supply if needed – and if needs be, can even fit them for you for a reasonable charge.
If you are into making your own cables, the new Harmony plugs have to be at the top of the list – the Copper Harmony plugs are completely affordable when compared to any other specialty RCA . If you are aiming to create something special, the better versions will thrill.
Who knows where this playing around with cables might lead – you could be the next Keith Eichmann. Whatever originally started KL on his path, he’s come a very long way and the plugs are only an introduction – if you really want to hear what is possible with these plugs, you have to check out his new KLEI gZero ICs – they are designed around the same principles as the plugs and then take things further – the better the cable, the better the plugs employed.
